Rosina Bulwer Lytton, Baroness Lytton, (née Rosina Doyle Wheeler; 4 November 1802 – 12 March 1882) was an Anglo-Irish writer who published fourteen novels, a volume of essays and a volume of letters. In 1827 she married Edward Bulwer-Lytton, a novelist and politician. Their marriage broke up, and he falsely accused her of insanity and had her detained in an insane asylum, which provoked a public outcry. He was made a baronet in the 1830s and was raised to the peerage in 1866; although she had separated from her husband she used the title Lady Lytton. She spelled her married surname without the hyphen used by her husband. Source: Wikipedia (en)
